A company has an email marketing tool that is used for both SMS and email. The tool generates the following campaign URLs: SMS link: www.website.com?cid=em:campaign_name-txt Email link: www.website.com?cid=em:campaign_name How should the Architect configure Marketing Channel Processing Rules to identify the SMS channel?

Marketing Channel processing rules are evaluated in order from top to bottom. The first rule that a hit matches gets credit, and subsequent rules are skipped. The SMS campaign URL (cid=...-txt) is a more specific version of the Email campaign URL (cid=em:...). To ensure SMS traffic is not incorrectly attributed to the more general Email channel, the specific rule for SMS must be placed above the Email rule. The correct condition for the SMS rule is to check if the query string parameter "cid" ends with "-txt".

A: Placing the SMS rule below the email rule would cause all SMS traffic to be incorrectly classified as Email, because it also matches the broader "starts with 'em:'" pattern. B: The condition "starts with 'em:'" is too general; it matches both email and SMS traffic. Placing it above the email rule would not properly distinguish SMS. D: This condition is too general, and the processing order is incorrect, leading to all traffic being misclassified as the first matching rule.
